    No Assembly Required: DNA brings carbon nanotube circuits in line

    Using DNA as a scaffold, researchers have devised a simple way of creating carbon nanotube transistors—a feat that paves the way for more complex circuits made from these nanomaterials.

  2. Earth

    Toxic cleanups get a boost

    Researchers have developed and field-tested a new technique that identifies specific soil microbes that can break down environmental pollutants.

  3. Tech

    Plastic Memories: Polymer materials store data permanently

    Researchers have fabricated a memory device that stores data permanently in electrically-conducting polymers.

  4. Underwater balancing act

    Researchers have identified a gene that influences the growth of crystals in the inner ears of zebrafish and found that modifying this gene can cause the fish to lose their sense of gravity.

  5. Materials Science

    Water Repellency Goes Nano: Carpet of carbon nanotubes cleans itself

    Forests of carbon nanotubes coated with Teflon yield a superhydrophobic material—the ultimate self-cleaning surface.

  6. Chemistry

    Clays catalyze life?

    Clay minerals at the bottom of the ocean may have played a crucial role in assembling the very first cells on Earth billions of years ago.

  7. Tech

    Timing Is Everything: Implantable polymer chip delivers meds on schedule

    A polymer microchip implanted under the skin could deliver multiple doses of medications at programmed intervals, eliminating the need for pills and injections.

  8. Chemistry

    The Nature of Things

    An earth scientist's proposed alternative periodic table of elements is emblematic of the growing desire among scientists to recast this 130-year-old chart.

  9. Chemistry

    Nobel Prize in Chemistry Opens Channels: Research reveals vital function of tiny pores in cell membranes

    The 2003 Nobel Prize in Chemistry honors two researchers for their pioneering work on the structure and mechanisms of cell membrane channels, tiny pores that regulate the flow of ions and water molecules across cells.

  10. Tech

    Special Delivery: Metallic nanorods shuttle genes

    A new gene therapy technique relies on nanorods made of gold and nickel to deliver genes to cells in the body.

  11. Materials Science
